Abstract

The teachers' awareness of students' learning obstacles is crucial in the reflective practice of developing effective didactic designs. The reflective practice of in-service Indonesian mathematics teachers in diagnosing students' learning obstacles is rising. However, despite the importance of diagnosing students’ learning obstacles for developing the teaching profession, there is little research evidence supporting strategies for mathematics teachers in Indonesia in diagnosing student learning barriers through the interview process. The purpose of this study is to analyze the interviewing strategies that mathematics teachers use in order to diagnose students’ learning obstacles. This research is a qualitative case study and employs thematic-content analysis. In-service high school mathematics teachers from three provinces in Indonesia to participate in this study. This study used video recordings of teachers conducting interviews to investigate students' learning obstacles, triangulated with teachers' reports. This findings show that the teachers' two main strategies are social-emotional and didactical-pedagogical strategies. This study present our expanded explanation of each strategy, as well as some suggestions for further research, intending to assist in establishing a culture of reflective practice among mathematics teachers as part of teachers' professional development.

Abstract

Complex life patterns in the 21st century require humans to master certain competencies and skills to adapt to life. Critical thinking ability is one of the important abilities to be mastered by today's students. This study aims to analyze the influence of culture-based discovery learning model learning. This type of research is quasi-experimental research. A total of 55 elementary schools and fifth-grade students were involved in this study. The experimental class consisting of 27 students was given treatment in the form of culture-based discovery learning, while the control class, which consisted of 28 students, was given conventional learning. Research data collection was carried out by giving tests of critical thinking skills in mathematics to two post-learning classes. Data analysis was carried out through descriptive data analysis and inference analysis through two independent sample t-tests with a significance level of 5%. The results showed significant differences in critical thinking skills between students taught through the culture-based discovery learning model and those taught through conventional learning models. The average critical thinking ability of students taught through the culture-based discovery learning model is higher than that of students taught through conventional learning models. It was concluded that the application of culture-based discovery learning can improve the critical thinking skills of elementary school students.

Abstract

Penelitian ini memiliki tujuan untuk menganalisis pembelajaran matematika berdasarkan Teori Situasi Didaktis atau Theory of Didactical Situation (TDS) materi Penyajian Data pada kelas VII. Kemudian penelitian ini juga melihat learning obstacle yang dialami oleh siswa dalam proses pembelajaran. Penelitian ini sebagai penelitian kualitatif dengan pendekatan atau jenis fenomenologi. Penelitian yang dilakukan di SMPN 15 Bandung ini memiliki subjek penelitian siswa kelas VII sebanyak 29 siswa. Teknik pengumpulan data yang dilakukan dengan observasi, pemberian tes tertulis, wawancara dan dokumentasi. Selanjutnya data yang diperoleh dianalisis berdasarkan Teori Situasi Didaktis yang mencakup aksi, formulasi, validasi dan institusionalisasi. Hasil penelitian ini yaitu ditemukannya situasi didaktis pada proses pembelajaran materi Penyajian Data di kelas VII SMPN 15 Bandung yang pelaksanaanya tidak cukup baik dan maksimal. Hal tersebut dapat dilihat dari setiap situasi didaktis yang tidak berjalan maksimal, dan learning obstacle dialami siswa meliputi: epistemological obstacle dengan siswa masih belum mampu memahami permasalahan yang disajikan pada diagram garis yang meminta siswa menjumlahkan setiap kenaikan pada diagram; ontological obstacle dengan siswa belum memiliki kesiapan belajar yang optimal dalam memahami dan mangaplikasikan konsep frekuensi dan nilai yang ada; dan didactical obstacle berupa pemahaman terkait pentingnya memberikan keterangan secara lengkap pada diagram belum sampai dengan baik kepada siswa.
